Skill Development based on Modular Employable Skills (MES)<br />
Background<br />
The need for giving emphasis on the Skill Development, especially for the less<br />
educated, poor and out <strong>of</strong> school youth has been highlighted in various forums. The skill<br />
level and educational attainment <strong>of</strong> the work force determines the productivity, income levels<br />
as well as the adaptability <strong>of</strong> the working class in changing environment. Large percentage<br />
<strong>of</strong> population in India is living below poverty line. One <strong>of</strong> the important causes is lower<br />
percentage <strong>of</strong> skilled persons in the workforce<br />
The skill development at present is taking place mostly in the informal way, i.e.<br />
persons acquire skill at the work-place when they help their parents, relatives and employers<br />
etc. Such persons do not have a formal certificate and thus earn lower wages and are<br />
exploited by employers. They have come through informal system due to socio-economic<br />
circumstances <strong>of</strong> the family and the compulsions <strong>of</strong> earning a livelihood rather than<br />
attending a formal course. While their productivity is low, their contribution to the national<br />
GDP cannot be ignored. If the country can create a system <strong>of</strong> certification which not only<br />
recognizes their skills but also provides education and training in a mode that suits their<br />
economic compulsions, it will not only benefit the workforce to earn a decent living but also<br />
contribute to the national economy by better productivity <strong>of</strong> this workforce.<br />
Another related problem to be tackled is large number <strong>of</strong> students drop outs (About<br />
63% <strong>of</strong> the school students drop out at different stages before reaching Class-X).<br />
Frame work for Skill Development based on ‘Modular Employable Skills (MES)’<br />
Very few opportunities for skill development are available for the above referred<br />
groups (out <strong>of</strong> school youth & existing workers especially in the informal sector). Most <strong>of</strong> the<br />
existing Skill Development programmes are long term in nature. Poor and less educated<br />
persons can not afford long term training programmes due to higher entry qualifications,<br />
opportunity cost etc. Therefore, a new frame work for Skill Development for the Informal<br />
Sector has been evolved by the DGET to address to the above mentioned problems. The<br />
key features <strong>of</strong> the new frame work for skill development are:<br />
Demand driven Short term training courses based on modular employable skills<br />
decided in consultation with Industry<br />
Flexible delivery mechanism (part time, weekends, full time)<br />
Different levels <strong>of</strong> programmes (Foundation level as well as skill upgradation) to meet<br />
demands <strong>of</strong> various target groups<br />
Central Government will facilitate and promote training while Vocational <strong>Training</strong> (VT)<br />
Providers under the Govt. and Private Sector will provide training<br />
Optimum utilisation <strong>of</strong> existing infrastructure to make training cost effective.<br />
Testing <strong>of</strong> skills <strong>of</strong> trainees by independent assessing bodies who would not be<br />
involved in conduct <strong>of</strong> the training programme, to ensure that it is done impartially.<br />
Testing & certification <strong>of</strong> prior learning (skills <strong>of</strong> persons acquired informally)<br />
2
The Short Term courses would be based on „Modular Employable Skills (MES)‟.<br />
The concept for the MES is :<br />
<br />
<br />
<br />
<br />
<br />
Identification <strong>of</strong> „minimum skills set‟ which is sufficient to get an employment in the labour<br />
market.<br />
It allows skills upgradation, multiskilling, multi entry and exit, vertical mobility and life long<br />
learning opportunities in a flexible manner.<br />
It also allows recognition <strong>of</strong> prior learning (certification <strong>of</strong> skills acquired informally)<br />
effectively.<br />
The modules in a sector when grouped together could lead to a qualification equivalent<br />
to National Trade Certificate or higher.<br />
Courses could be available from level 1 to level 3 in different vocations depending upon<br />
the need <strong>of</strong> the employer organisations.<br />
MES would benefit different target groups like :<br />
o Workers seeking certification <strong>of</strong> their skills acquired informally<br />
o workers seeking skill upgradation<br />
o early school drop-outs and unemployed<br />
o previously child labour and their familly<br />
Age <strong>of</strong> participants<br />
The minimum age limit for persons to take part in the scheme is 14 years but there is<br />
no upper age limit.<br />
Curriculum Development Process<br />
Following procedure is used for developing course curricula<br />
• Identification <strong>of</strong> Employable Skills set in a sector based on division <strong>of</strong> work in the labour<br />
market.<br />
• Development <strong>of</strong> training modules corresponding to skills set identified so as to provide<br />
training for specific & fit for purpose<br />
• Organization <strong>of</strong> modules in to a Course Matrix indicating vertical and horizontal mobility.<br />
The course matrix depicts pictorially relation among various modules, pre requisites for<br />
higher level modules and how one can progress from one level to another.<br />
• Development <strong>of</strong> detailed curriculum and vetting by a trade committee and by the NCVT<br />
(Close involvement <strong>of</strong> Employers Organizations, State Governments, experts, vocational<br />
training providers and other stake holders is ensured at each stages).<br />
Development <strong>of</strong> Core Competencies<br />
Possession <strong>of</strong> proper attitudes is one <strong>of</strong> the most important attribute <strong>of</strong> a competent person.<br />
Without proper attitudes, the performance <strong>of</strong> a person gets adversely affected. Hence,<br />
systematic efforts will be made to develop attitudes during the training programme.<br />
The trainees deal with men, materials and machines. They handle sophisticated tools and<br />
instruments. Positive attitudes have to be developed in the trainees by properly guiding<br />
3
them and setting up examples <strong>of</strong> good attitudes by demonstrated behaviors and by the<br />
environment provided during training.<br />
Some important core competencies to be developed are:<br />
1. Safety consciousness and safe working practices<br />
2. Care <strong>of</strong> equipment and tools<br />
3. Punctuality, discipline and honesty<br />
4. Concern for quality<br />
5. Respect for rules and regulations<br />
6. Concern for health and hygiene<br />
7. Cordial relationship and Cooperation with co-workers and team Work<br />
8. Positive attitude and behavior<br />
9. Responsibility and accountability<br />
10. Learn continously<br />
11. Communication Skills<br />
12. Concern for environment and waste disposal<br />
Following competencies should also be developed during level-II and higher courses:<br />
1. Ability for planning, organizing and coordinating<br />
2. Creative thinking, problem solving and decision making<br />
3. Leadership<br />
4. Ability to bear stress<br />
5. Negotiation<br />
Duration <strong>of</strong> the Programmes<br />
Time taken to gain the qualification will vary according to the pathway taken and will be kept<br />
very flexible for persons with different backgrounds and experience. Duration has been<br />
prescribed in hours in the curriculum <strong>of</strong> individual module, which are based on the content<br />
and requirements <strong>of</strong> a MES Module. However, some persons may take more time than the<br />
prescribed time. They should be provided reasonable time to complete the course.<br />
Pathways to acquire Qualification:<br />
Access to the qualification could be through:<br />
• An approved training programme; Or<br />
• A combination <strong>of</strong> an approved training programme plus recognition <strong>of</strong> prior<br />
learning including credit transfer; Or<br />
• The recognition <strong>of</strong> prior learning that provides evidence <strong>of</strong> the achievement <strong>of</strong><br />
the competencies for the qualification.<br />
4
Methodology<br />
The training methods to be used should be appropriate to the development <strong>of</strong> competencies.<br />
The focus <strong>of</strong> the programme is on “performing” and not on “Knowing”. Lecturing will be<br />
restricted to the minimum necessary and emphasis to be given for „hands on training‟.<br />
The training methods will be individual centered to make each person a competent one.<br />
Opportunities for individual work will be provided. The learning process will be continuously<br />
monitored and feedback will be provided on individual basis.<br />
Demonstrations using different models, audio visual aids and equipment will be used<br />
intensively.<br />
Instructional Media Packages<br />
In order to maintain quality <strong>of</strong> training uniformly all over the country, instructional media<br />
packages (IMPs) will be developed by the National Instructional Media Institute (NIMI),<br />
Chennai.<br />
Assessment<br />
DGE&T will appoint assessing bodies to assess the competencies <strong>of</strong> the trained persons.<br />
The assessing body will be an independent agency, which will not be involved in conducting<br />
the training programmes. This, in turn, will ensure quality <strong>of</strong> training and credibility <strong>of</strong> the<br />
scheme. Keeping in view the target <strong>of</strong> providing training/testing <strong>of</strong> one million persons<br />
through out the country and to avoid monopoly, more than one assessing bodies will be<br />
appointed for a sector or an area.<br />
Certificate<br />
Successful persons will be awarded certificates issued by National Council for Vocational<br />
<strong>Training</strong> (NCVT).<br />
